This story was a tie in to a previous supers game where I was
the primary GM. One of the other player/GMs in that introduced the
Legion and Senators. Since they were reality jumpers they were a
perfect fit for Nexus so I threw them in.

Frankly the story is lacklustre, but I think it had enough
to possibly prod some ideas into existence.

I come from a reality where the Human Roman Empire never fell.
It just kept going and going, until we evolved beyond our humanoid
forms and into what others call "giant blue bipedal ants." Then the
Legion took control and ousted the Senate.

My ancestors were Senators, and now I'm one. A refugee fleeing
across realities always away from the Legion. Sometimes I see them
in Nexus. Technically they can't hunt us here, but knowing the
Legion, they're preparing to conquer Nexus just like they have all
the other realities they've encountered.
